Application filed March 18, 19520. Serial No. 366,788

To all whom it may concern: I I

Be it known that I, ROBERT-P. Fnrn, a citizen of the United States of America, and resident or Marlboro, in the county of MiddleseX and State of Massachusetts, have in vented certain new and useful Improvements in Machines forhiaking Shoe Boxing-s, 01" which the following is a specification;

This invention relates to machines for making shoe boxings and has for its object the provision of novel means for applying liquid material which upon drying or cooling will solidify and reenforce or stiffen the fabric-in order that it may be used as boxings for shoes, and the invention consists an improvement on my Patent #l,236,832 of August 14', 1917.

The present-invention hast-he objects in view of producing the results and tune-- tions otthe said patei'it-ed'device but in a more expeditious and satisfactory manner and it furthermore has for its object to provide the novel means whereby the presser head is moved uniformly so as to obviate splashing of the fluid or undue agitation thereof while the presser head is moved into and out of the receptacle.

A further object of this invention is to provide novel means for yieldingly holding the mandrel with relation to which the presses head moves and coacts' and to simplify the construction whiclrminimizes the cost of production and maintenance.

With the foregoing and other objects in view, the invention consistsin the details of construction and in the arrangement and 'cou'ibination parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, re terence will be had to the accompanyingdrawing forming part of this specification wherein like characters denote corresponding parts in the several views, and in which- Figure 1 illustrates a sectional view of a machine embodying the invention;

. Figure '2 illustrates a front view partly in section;

Figure 3 illustrates an underneath plan view of a presser head;

Figure st 'llustrates a sectional view thereof; and a f Figure 5 illustrates a perspective view of the clutch operating lever.

.ln these drawings denotes a hollow standard having a suitable base or support i the said standin havin a curved upper end with a marginal flange, 12 and a web 13 closing the end of the standard except for the aperture 14 therein in which a mandrel rod 15 is slidable.

A housing comprising a casing 16 has a flange 1'7 secured to the flange 12 by fastenings 18, such as bolts and the said housing has a transversely disposed web 19 which is apertured to receive the mandrel rod so that the mandrel rod may reciprocate in the housing and in the end of the standard. An apcitured plate 20 is secured on the lower end oi the housing by t'astenings such as screws 21 and a mandrel 16 is arried on the lower end of the mandrel rod.

A collar 22 is secured near the upper end of the mandrel rod and is intended to engage the end of the standard to limit the movement of said mandrel rod and collars 23 and 2d are alsosecured on the mandrel rod for purposes to be presently explained.

A coiled spring is applied to the mandrel rod above the collar and is intended to operate as abutter or shock absorber when the mandrel ro'd has traveled a predetermined distance since when the said spring bears against the collar 23 and will upon upward movement of the mandrel rod strike the end of the standard and be compressed.

A spring 26 encircles the mandrel rod and l ars againstthe collar 9i and against the web 19 so that the mandrel rod is held normally depressed by the said spring. and

when the presser head moves upwardly it,

couununicates motion to the mandrel rod against the action of the said spring 26.

it plate 2? covers an aperture 28 in the standard and is secured to the said standard by tastenings :29 such as screws which pass through the plate and are threaded in the standard around the margin of the said plate. ipertured lugs 30 and 3i are carried by the plate and constitute guides for the rod 32 which is slidable the apertures ot' the said lugs. The plate 27 has a slot 33 which constitutes a clearance for the arm 34. which arm has an aperture to receive the rod 32 and the said rod is held at difierent positions of adjustment on the rod by means of the fastening 35 which may be in the nature of a set screw. As the rod 3:2 is reciprocatcd the arm is carried up and down such aitliustinents by a set screw 39.

collar also has a. wrist pm ll) proj ecting 'without creating agitation or splashing and the said arm has a down *ardly extending portion 36 which dips into the receptacle 3? adapted to contain-a solution to be applied to boxing-s of shoes which solutions when dried or hardened lends stiffness and rigidity to the said boxings.

The depending end 86 of the arm has the presser head thereon which is of improved construction compared with that of the patent and the said presser head of this device differs from that shown in the aforesaid patent in that the shield 92 has flat strips of metal 93 anchored to it at their ends and the said strips of metal extend under the plate 9% of the presser head and the said plate carries the cushion {)5 and these parts, except the strips of metal, correspond to the construction of the presser head of the patent, but in this form of invention I interpose springs 95 on the guiding rods 96 between the shoulders 98 and the strips of metal and have the guiding rods 96 on the said plate and connected thereto which travel through apertures 97 in the said strips of u'letal, the springs in this form yielding under ,)ressure when the presscr head is in cooperative relation with the mandrel and the material to be pressed and treated is between the presser head and tho mandrel. 'lhe springs just described perform somewhat the same function as the springs 26 of the patent.

Ti lie rod 32 has a collar 38 'attachedto it, the said collar being adjustable to different po itions thereon according to "the throw to be given the rod and the collar is held at This from it on which a link 41 is oscillatably monnteth the lower end of the said link being connected to a wrist pin 42 carried with the gear wheel. til. it is the purpose of the inventor to perhaps modify. the structural features of the wheel and the illustration shows the pret'erreiil en'ibodiment at this time.

A. spring -'l ;lci'icirclcs the rod 32 and is interposed between the collar 38 and the apertured lug 3i so that yielding action is afforded the rod as it is being reciprocated and. therefore, the presser head will move into the fluid contained in the receptacle i of the fluid.

A stud 4:5 is secured in an aperture 46 of the standard and the said stud constitutes a trunnion on which the wheel 4-3 is rotatable.

A. driven shaft 417 journaled in suitable hearings in the standard below the stud 4:5 and the said driven shaft has a pinion 48 secured. to it which meshes-with teeth of the gear wheel. 41 3 so that through these instrumentalities the gear wheel 43 is rotated.

The driven shaft 4i? has a pulley d9 rotatable on it and one face of the said pulley constitutes a clutch member 50 which is en gaged by a clutch member 51, keyed on the shaft 457 so that as the pulleyis reciprQ cated on the shaft, it is caused to engage or disengage the clutch member 51 and as the pulley is to be driven in any suitable manner by a belt or the like, its motion will be communicated to the mechanism of the machine when the clutch members are in engagement. The shaft 4? has a collar 52 secured to it by a fastening 53 such as a screw and said collar limits the motion of the hub 5a of the pulley 49 which hub is of course a part of the pulley and is moved on the shaft by the lever 55 which has a bifurcated end to embrace the hub. the said hub having a reduced portion which is spanned by the bifurcated end of the lover. The lever is oscillatably mounted on a pivot 56 and terminates in a pedal 57 by which it is moved in one direction, the said pedal end of the lever being elevated by a spring 58 which is connected to a stud 59 of the standard and to the said lever. 7

It will be understood from an inspection of the drawing and from the foregoing description that when power is applied and the pulley is rotated, the presser head will be moved into and out of thereceptacle 37 and into and out of coactive relation'vvith the mandrel so that when the material which is tohe stiffened for shoe boxings is interposed between the presser head and the mandrel, material carried from the receptacle by the presser head will be forced into engagement with the said material and that the device will operate with sufiicient force to cause the material being treated to be impregnated to a great extent by the fluid.

Owing to the yielding action of the fluid carrying presser head and themeans-for confining a certain amount of the fluid deli vered, it is in coactive relation to the material to be impregnated, the degree of efficiency of the fluid applying mechanism is very pronounced, and. of course; any fluid that is dislodged from the presser head or the material being treated finds its way to the receptacle so that there will be no waste.

I have provided a means for maintaining the fluid in the receptacle 37 at a predetermined level and to that end, I utilize a tank 60 having a spout 61 depending or extendi ng into the said receptacle 3'? and I have the tank air tight so that it is only by unsealing the end of the spout 61 that air may be admitted. The spout 61. is sealed by the fluid in the receptacle 37 and air sealed in the tank will prevent fiow of fluid from the tank until the fluid in the receptacle 37 recedes and again unseals the end of the spout and of course this result in automatic maintenance of the fluid at a predetermined level in the receptacle 37. V V i The mandrel rod 15 has a slot 15 in it to receive a screw 15* which'prevents rotation of the mandrel rod while at the same time permitting it to move vertically.

The receptacle 04 is adapted to hold the material which 18 adapted to be heated and the ordinary electrically heated pots used interior of thestandard by the removal of the said shields.
